That's OK Trav, next time you make it out there we will go and check it. I still for some reason have failed at finding the Royal Flush, so that is still on the list of going down and possible turning around and going up. I have been to Rack's "Royal Flush" but that is not the same one.
You really want to try and go up it? Go down it first then contemplate it. I have the GPS co-ordinates of the top of it somewhere around here. I will post it if I can find them. Was out there over New Years and we went up about 1/2 way. There were some crazy azz rock crawlers plugging up the trail towards the top so we didn't go any further nor did we really have any intentions to.
Let me know if you plan on going out there, it's a great place to ride. Down the flush then over to the sand hills for some Invader :-)
